Filed: 1942-12-21
Abstract: 559,140. Photographic cameras. KODAK, Ltd. Dec. 21, 1942, No. 18131. Convention date, Jan. 6. [Classes 97 (i) and 98 (i)] A concave reflector or other optical member serving as a collective and image forming member is carried by a movable member between the exposure frame and objective in a camera, and forms with the objective part of the view-finder system. In the camera shown, a concave reflector 16 carried by a truncated-conical shutter member 21 rotatably mounted on a pivot 23 forms, together with the objective, an image which after reflection from a mirror 17 at the front of the camera and inversion in a prism 18 is viewed through an eyepiece 19 in the rear wall of the camera. The mirror 17 is provided with a lens element 20. The shutter member 21 is formed with an exposure aperture 22, and on release operation of a trigger 14 is rotated through approximately a complete revolution to move this aperture past the exposure opening by means of a spring 25 operating through gears 32, 36. In a modification, the reflector 16 is replaced by a suitably formed portion of the metal shuttermember 21, and the mirror 17 has no lens element. The inverting prism 18 may be omitted.

[Also in Group XXXIV] A method of making a diaphragm for a tubeless tyre or for making tyres tubeless (see Group XXXIV) comprises building up a band from plies 6, 7 of rubber coated fabric on a drum, placing the band, with aluminium rings 11, having rubber strips 17, 13 enclosing the ends of the plies, on a drum 20, expanding an inflatable member 22 to shape the band. Removing the shaped band from the drum (see Fig. 8 not shown) and then vulcanizing the band with the aid of an air bag 28, Fig. 9, in a two-part mould hinged at 31. The mould has aluminium base rings 34 having channels 39 through which during vulcanization heating fluid is circulated, and just prior to the opening of the mould and whilst the mould is open, cooling fluid is circulated, to bring the base rings to room temperature before the next diaphragm is inserted. The base rings may be heated to a higher temperature than the mould sections. When the mould is opened, fluidpressure actuated knock-out pins 40 free the diaphragm from the base rings.

Title: Improvements in or relating to Thin Film Circuit Devices.
Inventor: MADDISON JOHN CLARK
IPC: H01L49/02
Filed: 1966-04-28
Abstract: 1,180,928. Capacitors. PLESSEY CO. Ltd. 25 April, 1967 [28 April, 1966], No. 18584/66. Heading H1M. A thin film capacitor having a required capacitance is made by forming a capacitor of nominal size an electrode 2 of which is so shaped that it comprises a main area 4 connected in parallel with smaller areas 5, 6, 7, 8 and 9 such that the sum of the capacitances of the smaller areas and the main area is at least equal to the required capacitance, and taking as many of the smaller areas out of circuit as will bring the capacitance of the remaining combination to the required value. Aluminium electrode 2 deposited on glass substrate 1 is covered with a dielectric layer, e.g. silicon monoxide and a rectangular second aluminium electrode. The areas 5 to 9, are preferably in geometric progression, e.g. 16, 8, 4, 2 and 1% of area 4. To adjust the capacitance value, the capacitor is passed through a series of machines the first of which determines whether or not is value greater than 116% of the required value. If it is, a mechanical diamond-headed scriber cuts out capacitor 5 and the capacitor passes to the second machine which determines whether or not its value is greater than 108% of the required value and so on, the value eventually achieved being within 1% of the required value. For ease in masking the electrode may be deposited as a main area separated from the smaller areas, and then electrically connected thereto by deposited thin films of e.g. gold (Fig. 2, not shown). The counter-electrode may be deposited so that there is an unmetallized strip where one section will pass (Fig. 3, not shown).

Abstract: 423,503. Cigarette-making machines. MOLINS, W. E., 2, Evelyn Street, Deptford, London. July 4, 1933, No. 18937. [Class 130] Filter plugs or wads, for example for use with cigarettes, are formed from strips of compressible material which are extensible transversely of their length, and substantially of the same thickness as the plugs, by compressing the longitudinal edges of the strips to form the required cross-section of plug. The strips 1, Figs. 1 and 11, are cut from a web or sheet of material and delivered end-toend on to a conveyer, which may consist of a continuous web 2 of wrapping material, which is wrapped about the strips to form a continuous rod for cutting into lengths as indicated by the chain lines in Fig. 1, the lengths including the joins 4 being deflected to one side and discarded. The strips may abut end to end, or may overlap at the ends. The material, such as crepe paper or cellulose wadding, is fed from a roll 5, Fig. 6, over a table 6 to knives 9, 10, which may be blunt so as to compress the material along the line of severance and give the strips cut off an oval form, as shown in Fig. 11. These may afterwards be further compressed to the circular form if desired. The strips are delivered to a rotatable fluted wheel 16, and are removed therefrom by a swinging gripper 18, Fig. 5, oscillated by a crank disc 19, which delivers the strips on to the wrapping material 2 at the same; speed as this is moving along the trough 3. A compression wheel 22, forming-mechanism 23, and pasting-device 24 then complete the formation of the continuous rod, which is cut into plug lengths by a cutter 26, the undesired portions at 4 being deflected by mechanism 27, which may be the same as that described in Specification 421,551. According to the Provisional Specification, the strip material may be folded into several superimposed layers after the manner of a fan, or in spiral form.
